Method for Transmitting/Receiving a Machine Type Communication Physical Downlink Control Channel

2. The method of claim 1, wherein the MPDCCH is mapped based on an identical mapping pattern in the at least one first symbol to which the MPDCCH is additionally mapped and the at least one second symbol to which the MPDCH is initially mapped.

3. The method of claim 1, wherein a cell-specific reference signal is mapped to an identical RE in the at least one first symbol to which the MPDCCH is additionally mapped and the at least one second symbol to which the MPDCH is initially mapped.

4. The method of claim 1, wherein a first slot in the subframe includes the control region and a data region in which the MPDCCH or a Physical Downlink Shared Channel (PDSCH) is transmitted.

5. The method of claim 4, wherein rate matching is performed in the data region in preference to the control region.

6. The method of claim 1, wherein a channel estimation of the MPDCCH is performed using a channel estimation result of at least one other subframe contiguous to the subframe.

8. The terminal of claim 7, wherein the MPDCCH is mapped based on an identical mapping pattern in the at least one first symbol to which the MPDCCH is additionally mapped and the at least one second symbol to which the MPDCH is initially mapped.

9. The terminal of claim 7, wherein a cell-specific reference signal is mapped to an identical RE in the at least one first symbol to which the MPDCCH is additionally mapped and the at least one second symbol to which the MPDCH is initially mapped.

10. The terminal of claim 7, wherein a first slot in the subframe includes the control region and a data region in which the MPDCCH or a Physical Downlink Shared Channel (PDSCH) is transmitted.

11. The terminal of claim 10, wherein rate matching is performed in the data region in preference to the control region.

12. The terminal of claim 10, wherein a channel estimation of the MPDCCH is performed using a channel estimation result of at least one other subframe contiguous to the subframe.

14. The method of claim 1, wherein the subframe is a special subframe in which a number of symbols for data transmission among symbols in a subframe is less than a certain number.
